Want to increase your website's presence on Google? Don't waste your time littering your site with "keywords" meta tags, because according to Google, that won't do you a bit of good.

In a blog post on Monday, Google explained that it doesn't use keyword meta tags, disregarding them completely. The reason, Google says, is because meta tags are subject to abuse. It's far too easy (and common) for a webmaster to inject oft-irrelevant keywords without typical visitors ever seeing them, so Google has been ignoring them for "many years."

The search giant also clarified that it doesn't ignore all meta tags, such as sometimes using the "description" meta tag as the text for its search results snippets. However, these too are disregarded in terms of ranking.
